Product Description

NECH Series Evaporative Condenser/ Closed Cooling Tower
NECH The NECH Series, a staple among evaporative condensers, is renowned for its innovative mixed flow heat transfer system. This impressive design ingeniously combines a vertical cross-flow of air and refrigerant steam, ensuring optimal airflow distribution throughout the condenser. As a result, this sophisticated engineering marvel delivers significantly enhanced heat exchange efficiency, making it an ideal choice for industrial applications where performance and reliability are paramount.

Advantages

 

· Experience unmatched efficiency with our Mixed Flow Heat Transfer, delivering superior condensation performance.
The innovative vertical cross-flow design ensures air and refrigerant steam interact optimally, guaranteeing even airflow through the condenser for exceptional heat transfer.

· Benefit from secondary heat transfer for enhanced cooling effectiveness.

Our advanced design allows spray water to flow through the condenser coil, engaging in an initial heat exchange. Followed by passage through the lower PVC heat exchange layer for a secondary process, it culminates in a collection basin, optimizing cooling efficiency through recycling.

· Closed circuit system promotes Energy Efficiency and Eco-Friendly Operations.

By condensing gaseous refrigerant within a closed coil system, our product maintains purity, reduces water use and maintenance expenses, and extends the lifespan of your equipment.

· Thoughtfully designed compact structure for Robustness and Ease.

Boasting minimal space requirements, our design simplifies shipment, installation, and maintenance, providing unparalleled convenience.

 

Work Principle

When the NECH evaporative condenser elegantly springs into operation:
The robust condensing coil stands as the principal conduit for refrigerant steam, artfully transforming this vapor into liquid by a sophisticated process of evaporative cooling and heat absorption through a delicate cascade of spraying water. The spray water gracefully flows through the coil unit, further journeying into the innovative PVC heat exchange system, where it continues its secondary heat transfer mission with seamless efficiency. Simultaneously, the high-performance axial flow fan delivers powerful propulsion, creating a cross flow of air within the condenser, perfectly synchronized to exchange heat with the refrigerant steam, thereby achieving stellar condensation performance with unmatched efficiency.

Instructions for Selection
1. Begin by confirming the condensing temperature and current wet bulb temperature. These are crucial parameters to ensure optimal performance.
2. Proceed to calculate the total heat abstraction amount. This is the total heat load that moves through the system to the condensers, ensuring effective thermal management.
3. Refer to either Table 2 or Table 3 to select the appropriate heat abstraction amount correction index. These tables are essential for accurately adjusting thermal loads.
4. Multiply the total heat abstraction amount by the selected heat correction index to determine the condensing load under actual working conditions. This step is vital for precise calibration.
5. Consult the Graph Specification sheet to choose a heat abstraction amount data value that is equal to or greater than the corrected data. This ensures that your selection aligns with operational requirements.
